System Peak Demand was 46,232 MW on July 27, 2016
Rapid DER deployment is spurring a democratized and decentralized system
calling for enhanced coordination at the T&D interface.
Diverse end-use devices and diverse owners/operators affect:
o Load shapes, peak demand, total energy consumption
o Energy flows, voltage variability, phase balance
o Variability and unpredictability of net loads and grid conditions
CAISO “sees” DER as if located at T&D substations
– No ISO visibility to distribution grid conditions/impacts
– Distribution utility is unaware of DER bids and dispatches
DER providing services to customers and the distribution
system affects the T&D interfaces
– Need accurate operational forecasting and local management
of DER variability to ensure end-to-end feasibility

• Each tier only needs to see
interchange with the next tier above &
below, not the details inside other tiers
• ISO focuses on regional bulk system
optimization while DSO coordinates
DERs
• Layered control structure reduces
complexity, allows scalability, and
increases resilience & security

Food for thought as we move into a high-DER future...
• Enabling Multi-use Applications of DER
– What grid services can be valued and stacked?
– Who has primacy over the resource in what situations?
– How to prevent double counting of capacity or resource capabilities?
– Net energy metering interactions and impacts on multiple-use applications
• Assessing DER Performance and Evaluation Methods
– Retail/wholesale metering interactions and adjustments needed.
– Sub-metering issues, rules, and manipulation concerns/
– Accounting for and removing the “typical use” of devices to ensure no double payments when selling specific grid services.
• Understanding DER Modeling and Optimization Techniques
– Setting and managing aggregate DER resource distribution factors in network models, i.e. how much expected output from each Pnode?
– How to account for the dynamic nature of DER when resource configurations and capabilities can vary greatly over time?
– How to model and manage storage device state of charge constraints?
– How to manage resource use limitations beyond 24 hour optimization horizons
• Agreeing on the Best System Architecture Design
– How to properly model and forecast interactions at the T&D interface?
– How to properly model micro-grids/Nano-grids?
– What is the most elegant system architecture to employ in a high-DER future? A Nested architecture or ?
• Coordinating Actions and Information at the T&D Interface
– How to ensure feasible dispatches from ISO to end-use customer
– What are the essential roles and responsibilities of key players at the T&D interface?
– What information must be exchanged and in what timeframes?
• Addressing Station Power Rules and Regulations
– How to treat station power when storage device is in charging mode?
– How to avoid double charging for station power at retail and wholesale level in behind the meter applications?
